And while it is possible the original fork had 43/45mm of rake it is just as possible it had more. And of course then you can choose the kind of fork crown that will match the frame. Fork blades come in different wall thicknesses and replacement forks tend toward the too heavy side as a safety feature. And then there is the question of whether you want one, two or no eyelets.
Doug, Is there anything like a registry of independent frame builders? I like the idea of supporting a local frame builder. My general impression (I know, not good to generalize...) is that many of the best frame builders are backlogged and may not be willing to take on a one-off fork when other full builds are in the queue. If I was in need, I'd be happy to throw some business to one of former your pupils, too.
Another thing I've wondered is how you might go about matching a fork to a frame that is sold without a fork. I've always been reluctant to buy a frame sans fork because I assume it may have been crashed, but also because I'm not sure how a non-original fork might affect the ride. Any thoughts or guidance?
